Trump administration lifts restrictions on Anthropic's Claude models after cybersecurity alarm

The Trump administration has lifted restrictions on Anthropic's Claude Fable 5 and Mythos 5 AI models after cybersecurity concerns led to a temporary ban. Anthropic now offers Fable 5 widely and Mythos 5 to U.S.-approved organizations, while OpenAI restricts its GPT-5.6 Sol model at the administration's request. President Trump's executive order on AI oversight requires vetting advanced systems before public release.
